Slove the system of substitution

y=x-8

y=2x-4

x + y = 4 ,  x − y = 2

x + 2 y = 4 ,  x − y = − 3

x 2 − y = 2 ,  2 x − y = − 1

Step-by-step explanation:

x=-4

Step-by-step explanation:

x-8=2x-4

+8        +8

x=2x+4

-2   -2

-x=4

-1    -1

x=-4

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
